Generate solar power. Store efficiently. Reduce costs.
If you use solar energy to generate environmentally friendly electricity, you are protecting the climate and environment and will easily minimise your consumption costs. Start a future-oriented energy supply with a photovoltaic system.
How does a solar power system work?
Solar power systems consist of modules with many small solar cells. They can be installed on the roofs or façades of buildings as well as on the ground. They convert solar energy into either heat or electricity and have become increasingly efficient and cheaper in recent years. By the way, the conversion of solar energy does not generate any CO2 or consume any fossil fuel: Solar power systems are therefore completely climate- and eco-friendly.
What are the advantages of a solar power system?
With a solar power system, you not only increase the value of your property but also become less dependent on the energy market and reduce your consumption costs. This should make you feel particularly good about the future, because by choosing a sustainable energy source you of course protect the climate at the same time.
What types of solar power systems are there?
There are essentially two types: Solar heating and photovoltaic systems.
Solar heating installations consist of collectors that contain a special carrier fluid. The sun heats the liquid, which then carries the heat to a storage facility. This heat can then be used to heat water and for heating purposes.
Photovoltaic systems convert solar energy into direct current in their solar cells. An inverter then transforms this into alternating current, which is then available at every socket. If too much electricity is generated, it can be either stored or fed into the general power grid.
How does a photovoltaic system work?
A photovoltaic system has various components: the solar modules with many solar cells, an inverter, an electricity meter, and often also an electricity storage system.
The actual transformation takes place in the solar cells: When sunlight hits the doped semiconductors, electrons are stimulated. This means electricity begins to flow and is then fed to the house via power cables. The inverter converts the direct current generated in the solar cells into the alternating current required in the home. This can either be consumed immediately, stored in an electricity storage system, used to charge an electric vehicle, or fed into the general power grid.
What is the best solution for you?
To find the right photovoltaic system for your home, you need to take various factors into account, such as the average annual electricity consumption and the roof area you have available.
Consumption data
Ensure that the photovoltaic system covers at least your own consumption. If you want to scale up, you can also use the electricity generated for e-mobility, store it, or feed it into the grid.
Roof texture
It is not just the roof's surface area that is decisive, but its orientation (north/south or east/west) and condition are also important. You can also choose between an on-roof or in-roof system.
How can you use solar power?
For a photovoltaic system, you can basically choose whether you prefer to consume the solar power produced on your roof or feed it into the grid.
With a system designed for own consumption, you mainly use or store the solar power in your home. Only if you generate more electricity than you need does the surplus get fed into the grid. You will, of course, be remunerated for this.
Once you have opted for direct feed-in, you supply all electricity you generate yourself into the grid. Primeo Energie then covers your own electricity consumption. This is why you need two electricity meters – to measure the solar power fed in as well as the power you receive yourself. In general, however, we recommend a photovoltaic system that is designed for own consumption when you purchase a new system. We would gladly advise you.
Two advantages: Solar power system with power storage
The sun is highest in the sky at noon – that’s when your photovoltaic system generates the most electricity. However, own consumption is not particularly high at this time.
To have enough power available at night or during bad weather, we recommend using an electricity storage system. Without such a system, you will have to feed the surplus into the grid, for example starting on noon.
The more electricity you store yourself and use later, the faster your system pays for itself and the lower your electricity bill.
What types of storage exist?
You can use two connection types if you want to add an efficient electricity storage system to your photovoltaic system:
AC-coupled storage: AC stands for alternating current. This type of storage has its own inverter or generator, which you can use for loading and discharging. In other words, it is independent of the photovoltaic system.
DC-coupled storage: DC stands for direct current. This type of storage unit is connected to the common inverter or generator on its DC side in parallel with your photovoltaic system.
Please note: Regardless of the type of storage, you must have a connection request and an installation notification to install a storage system. Both must be submitted to Primeo Energie by a licensed electrician. When planning and installing the storage unit, the technical plant regulations as well as the technical connection conditions (TCC) and other supplementary provisions of Primeo Energie must be strictly observed.
